Go language has a wide range of application fields: Do you know what projects can be developed with Go?
In recent years, the Go language has attracted much attention in the field of software development. With its concise and efficient features and syntax, it has gradually become the preferred programming language for developers. In addition to being used for web development and server programming, the Go language can be applied to a variety of different projects. This article will introduce some common Go language projects and provide corresponding code examples.
package main import ( "fmt" "net" ) func handleConnection(conn net.Conn) { buffer := make([]byte, 1024) length, err := conn.Read(buffer) if err != nil { fmt.Println("Error reading:", err.Error()) return } fmt.Println("Received message:", string(buffer[:length])) conn.Write([]byte("Message received.")) conn.Close() } func main() { listener, err := net.Listen("tcp", ":8080") if err != nil { fmt.Println("Error listening:", err.Error()) return } for { conn, err := listener.Accept() if err != nil { fmt.Println("Error accepting:", err.Error()) return } go handleConnection(conn) } }
package main import ( "fmt" "time" ) func producer(queue chan<- int) { for i := 0; i < 10; i++ { queue <- i fmt.Println("Produced:", i) time.Sleep(time.Second) } close(queue) } func consumer(queue <-chan int) { for num := range queue { fmt.Println("Consumed:", num) time.Sleep(time.Second) } } func main() { queue := make(chan int) go producer(queue) consumer(queue) }
package main import ( "database/sql" "fmt" "log" _ "github.com/go-sql-driver/mysql" ) func main() { db, err := sql.Open("mysql", "username:password@tcp(127.0.0.1:3306)/database") if err != nil { log.Fatal(err) } defer db.Close() rows, err := db.Query("SELECT id, name FROM users") if err != nil { log.Fatal(err) } defer rows.Close() for rows.Next() { var id int var name string err := rows.Scan(&id, &name) if err != nil { log.Fatal(err) } fmt.Println(id, name) } err = rows.Err() if err != nil { log.Fatal(err) } }
package main import ( "github.com/gin-gonic/gin" ) func main() { r := gin.Default() r.GET("/", func(c *gin.Context) { c.JSON(200, gin.H{ "message": "Hello World!", }) }) r.Run(":8080") }
The above are just some common application areas. In actual development, the Go language can be applied to more projects, such as distributed systems, blockchain applications, machine learning, etc. I believe that as everyone has a deeper understanding and mastery of the Go language, it will bring its advantages into more projects. Whether in terms of project performance, simplicity or development efficiency, Go language is a powerful tool.
